What on earth is a P.O.D.? Well it could be a space craft, but in this case it is Print On Demand.

PRLog (Press Release) – Mar 04, 2008 – With new printing techniques it has become possible to get rid of the minimum orders and set-up fees demanded by traditional printers like screen printers and embroiderers and makes it easier to print single items such as t-shirts, books and mousepads among hundreds of other products.
PODs are springing up in many countries such as www.zooicidal.com.au in Australia, www.printfection in USA, www.lulu.com in USA, Artsnow.com in China, and .
Print on demand businesses use direct to fabric and sublimation printing to print individual items which people can have printed as gifts or even to sell and make a small income for themselves. They offer products such as t-shirts, books, cushions, underwear, ceramics and keyrings, as well as more unusual items such as watches and handbags.
Many of these businesses also offer a web site of your own so you can sell items with your designs printed on them. It is a great way to make some pocket money, or a way to offer promotional items for your club or school.
The personalised gifts that you can have printed at these online businesses are truly unique. You could buy a 'I love Grandma' mug at your local store, one that hundreds of thousands of other people around the world are also buying, but if you have a photo of the grand kids or their school painting printed on a mug, it truly comes from the heart, and it is a gift that is a one-off, something no-one else can buy in any shop.
Try it for yourself, it is often free to uses these businesses and the end product is only a little dearer than buying something that is mass produced.
